履带拖拉机牵引24/48行播种机作业时,履带道板结层(占有效播种面积的8%)直接影响着播种质量。我们曾进行过各种改装,但效果不理想。1991年,采取附加深松杆齿的办法,松土效果良好。具体做法如下:在拖拉机与播种机之间,即联接器的横梁上(或三角架上),正对着两履带道位置处,各卡装上两个(或一组)中耕机杆齿,前后交叉排列,并在杆齿的后面挂上一组小钉齿耙。安装时须注意,杆齿的入土深度不可过大,一般在6～8厘米即可,以免转弯时损坏零件。此办法也可用在液压平地机等作业机械上,效果均佳。
Crawler tractor traction 24/48 row seeder operation, track layer layer (8% of the effective sown area) directly affects the planting quality. We have carried out a variety of modifications, but the effect is not satisfactory. In 1991, the method of attaching deep pine rod tooth was adopted, and the effect of loose soil was good. The method is as follows: between the tractor and the seeder, that is, on the beam of the coupler (or on the tripod), facing the positions of the two crawler tracks, two (or one) Before and after the cross-arrangement, and in the back of the rod to hang a group of small tooth rake. Must pay attention to the installation, pole tooth penetration depth can not be too large, usually 6 to 8 cm, to avoid damage when turning parts. This method can also be used in hydraulic grader and other operating machinery, the effect is good.
